NAME
       lvmdump - create lvm2 information dumps for diagnostic purposes

SYNOPSIS
       lvmdump [-a] [-c] [-d directory] [-h] [-l] [-m] [-u]

DESCRIPTION
       lvmdump	is  a  tool  to	 dump various information concerning LVM2.  By
       default, it creates a tarball suitable  for  submission	along  with  a
       problem report.

       The content of the tarball is as follows:
       - dmsetup info
       - table of currently running processes
       - recent entries from /var/log/messages (containing system messages)
       - complete lvm configuration and cache (content of /etc/lvm)
       - list of device nodes present under /dev
       - list of files present /sys/block
       - list of files present /sys/devices/virtual/block
       - if enabled with -m, metadata dump will be also included
       -  if  enabled  with -a, debug output of vgscan, pvscan and list of all
       available volume groups, physical volumes and logical volumes  will  be
       included
       - if enabled with -c, cluster status info
       - if enabled with -l, lvmetad state if running
       - if enabled with -u, udev info and context

OPTIONS
       -a     Advanced collection.  WARNING: if lvm is already hung, then this
	      script may hang as well if -a is used.

       -c     If clvmd is running, gather cluster data as well.

       -d directory
	      Dump into a directory instead of	tarball	 By  default,  lvmdump
	      will  produce  a	single	compressed  tarball containing all the
	      information. Using this option, it can  be  instructed  to  only
	      produce the raw dump tree, rooted in directory.

       -h     Print help message

       -l     Include  lvmetad(8)  daemon dump if it is running. The dump con‐
	      tains cached information that is currently stored in lvmetad: VG
	      metadata,	 PV  metadata  and  various  mappings in between these
	      metadata for quick access.

       -m     Gather LVM metadata from the PVs This  option  generates	a  1:1
	      dump  of	the  metadata area from all PVs visible to the system,
	      which can cause the dump to increase in size considerably.  How‐
	      ever,  the  metadata  dump  may  represent a valuable diagnostic
	      resource.

       -u     Gather udev info and  context:  /etc/udev/udev.conf  file,  udev
	      daemon  version  (output	of  'udevadm info --version' command),
	      udev  rules  currently  used   in	  the	system	 (content   of
	      /lib/udev/rules.d	 and  /etc/udev/rules.d	 directory),  list  of
	      files in /lib/udev directory and dump of current	udev  database
	      content (the output of 'udevadm info --export-db' command).

ENVIRONMENT VARIABLES
       LVM_BINARY
	      The LVM2 binary to use.  Defaults to "lvm".  Sometimes you might
	      need to set this to "/sbin/lvm.static", for example.

       DMSETUP_BINARY
	      The dmsetup binary to use.  Defaults to "dmsetup".
